    • A method of constructing a voided drilled shaft concrete structure is provided. Drilled shafts are large-diameter cast-in-place concrete structures that can generate extremely high temperatures during the concrete hydration/curing phase. When this temperature exceeds safe limits, the concrete does not cure correctly and will ultimately degrade. Minimizing the peak temperature (and the associated defects) can be undertaken by casting the shafts without concrete in the core (forming a void) thereby removing a large amount of energy producing material in a region that is least likely to benefit the structural capacity and that is less able to dissipate the associated core temperatures due to the presence of the more peripheral concrete.
    • 提供了一种构造空心钻井混凝土结构的方法。 钻杆是大直径现浇混凝土结构,在混凝土水化/固化阶段会产生极高的温度。 当该温度超过安全限度时,混凝土不能正确固化,最终会降解。 峰值温度(和相关缺陷)最小化可以通过铸造轴上没有混凝土的轴(形成空隙)来实现,从而在最不利于结构能力的区域中除去大量能量产生材料, 由于存在更多的周边混凝土,所以不太能够消散相关的核心温度。
